Introduction: Bullying is the misuse of power and old-known phenomena. The aim of this survey is Standardization of Olweus Bullying Questionnaire in Iran.

Methods: This is a descriptive survey which addresses Standardization of Olweus Bullying Questionnaire. To determine the reliability of the questionnaire، 28 students (16 girls and 12 boys) were tested .The scores of the above test was obtained using testretest method and Cronbach›s alpha، and its correlation is analyzed by SPSS software to answer the researchs′ questions. The significance level was considered P < 0.05.

Results: The correlation coefficient of twice implementation of the test in the section of «general questions about victimhood، bullying and attitude toward bullying» are all significant (P < 0.05)، except for subscale of victimization in groups of boys and girls .The results reveal that there is a significant correlation between subscales of victimization/bullying in the sample and group of boys. This value was not significant in the group of girls.

Conclusions: Overall، the evidence shows that the Olweus bullying questionnaire has proper psychometric properties and can be used in Iranian population.

Introduction: Effect of potassium (K) and mulch materials on grading of different types of tuber were investigated at the Agronomy research field of Sher-e-Bangla Agricultural University، Dhaka، Bangladesh during the period from November 2013 to March 2014.

Methods: The experiment comprised of four different doses of K viz.، 0 kg K ha-1، 100 kg K ha-1، 125 kg K ha-1، 150 kg K ha-1 and four different types of mulch materials viz.، soil mulch، rice straw، water hyacinth and saw dust. The experiment was laid out in a splitplot design with 3 replications. Statistical analysis done by using MSTAT-C program and mean differences among the treatments were compared by Least Significant Difference (LSD) at 5% level of significance.

Results: Maximum large sized tubers were produced by 150 kg K ha-1 with rice straw mulch. Application of 125 kg K ha-1 with rice straw produced maximum seed potato and tuber for French fry. Without K and soil mulch produced highest tuber for chips (% by t ha-1).

Conclusions: Application of 125 kg K ha-1 with rice straw mulch seems to be more suitable for getting higher seed potato (% by number and % by weight) and French fry for BARI (Bangladesh Agricultural Research Institute) TPS-I.

Results: The rate of attempt to cheating in boys and girls was 60% and 50 % respectively. Results showed that all dimensions of personality traits except openness to experience in boys، and conscientiousness in girls predicted cheating attempt (Self-efficacy explained 20% of variance of tendency to cheat in boys، and 15% in girls).

Conclusions: It can be concluded that there is a relationship between academic selfefficacy and big personality traits.

Adsorptive removal of toxic compounds makes practical and effective use of modified bentonite composite is a standout amongst the most appealing methodologies. Lately، the modified bentonite، a subset of advanced porous nanostructured materials، due to their unique characteristics are demonstrating awesome guarantee for better adsorption of different water contaminants. Given the significance of organic and inorganic removal، as a vital class of pollutants، this research article intends to review and summarize، quickly the as of late published research on the adequacy of various modified bentonite adsorbents under different physico-chemical process parameters in organic and inorganic contaminants adsorption. The impact of pH، the adsorption mechanism and the applicability of various adsorption kinetic and thermodynamic models are briefly discussed. The vast majority of the outcomes watched demonstrated that the adsorption kinetic and isotherm mostly followed the pseudo-second order and Langmuir models respectively.

Introduction: Brachiocephalic artery rupture is a very rare and fatal condition in dogs that is likely to be missed during clinical examination and would normally be diagnosed at post mortem. The aetiology is unknown but is most likely multifactorial and associated with arterial wall degeneration leading to rupture and sudden death due to massive haemorrhage resulting in death from hypovolemic shock.

Conclusions: A definitive diagnosis of fatal brachiocephalic artery rupture was reached at post-mortem examination، performed pro-bono، out of interest with the owner’s permission. Ante-mortem diagnosis of brachiocephalic artery rupture is still an unsolved challenge for the practising veterinarian، notwithstanding the recent advances in diagnostics. Fatal brachiocephalic rupture is a rare condition and only has been reported in dogs twice previously.

Introduction: Botulinum toxin (BTX) type A is now the most often used medicine with an excellent result for upper facial rejuvenation.

Case Presentation: This article represents one of the rare adverse effects of the Botulinum toxin type A for cosmetic use in a 50 years-old woman with moderate to severe peri-orbital rhytides. She received four injection of botulinum with six to twelve more interval and 1- day after last injection، she developed mid frontal recurrent episode edema، which spontaneously remitted.

Conclusions: Adverse effects of the Botulinum toxin type A for cosmetic use، should be considered before administration.
